Are " they " worth it ?
Thomasheisig has mentioned the current series. I can speak for the one before it.
The SK5A is a great-sounding preamp and usually a great buy. Like the current series 7 models, it is a (transistor) unit that tends to make you forget the tube-solid state distinction. If you have vinyl, its phono section will please you because it will adapt to any cartridge.
Stan Klyne still repairs the SK5A AFAIK, although some parts may no longer be available.
